This disclosure relates to coatings and, more particularly, to coating systems having improved durability.
Turbine engine components, such as airfoils, and other types of articles typically operate in severe environments. For instance, an airfoil may operate under high temperatures, corrosive conditions, and a variety of different stresses. The article may include a coating for protecting against the environmental conditions. The article may also include a bond coat under the protective coating to promote adhesion between the protective coating and the underlying substrate of the article.
